Abstract

A mixed method using both Whitney and linear edge elements for eddy current finite element analysis is described in this paper. The accuracy of the results obtained by the proposed mixed method are the same as those obtained using linear edge element. However, this method has shorter computation time and needs less computer memory than the finite element method based on linear edge element. In the same time, the results obtained by our method are better than those obtained by the finite element method using Whitney edge elements. The proposed method is successfully applied in benchmark models for eddy current nondestructive testing.
